Ladies/Gentlemen, My name is Anthony and I've been a lurker on these forums for some time. By trade, I am a heavy equipment mechanic. Recently, I purchased a 2014 F150 4x4 with the 3.5L Ecoboost engine - thus far, I'm in love with it. After browsing the forums, I read the numerous concerns about fuel dilution on these engines. Similarly, on many new tier 4 Diesel engines that use in-cylinder fuel dosing to burn soot from the DPF, fuel dilution of the oil has become a concern. Some manufacturers have responded by increasing the capacity of their oil pans, whereas others have chosen the "wait and see what happens" attitude and left their oil capacities/drain intervals unchanged. In my opinion, I only begin to care about fuel dilution as it relates to the presence of increased wear metals in the UOA. For my new truck, I have chosen to run 5w30 Pennzoil Ultra Platinum with an OCI for 5000mi. I chose this oil for the following reasons: 1. Picked up 6gal from Wally World for $27 per gallon, which seems like a good deal. 2. It meets the Ford specification outlined in my owners manual 3. According to info on this board, the additive package in this oil seems to handle fuel dilution better than others As for the filter, I typically use OEM products - in this instance, the Motorcraft FL-500s is what I will be using. At 960miles, I performed the first oil change - the truck currently has around 3800 miles. at 5960 miles, I will send an oil sample to Oil Analyzers, Inc. and report the results here. I'm curious as to what the reports will show. Thanks for your indulgence!
